Fan clutch wrenches are tools designed to remove and install fan clutches, which are components in a vehicle's cooling system. Fan clutches are attached to the front of the engine and engage when the temperature rises, spinning the fan to draw air through the radiator and cool the engine. When the engine cools down, the fan clutch slips and disengages, so the fan only runs when needed. Fan clutch wrenches come in different sizes and designs, and are made of hardened steel to withstand the force required to remove the nut that fastens the fan clutch to the engine.

Using a fan clutch wrench with an impact hammer
A fan clutch wrench is a tool that can help you remove or install a fan clutch when repairing a water pump or fan clutch. It is designed to fit over the large nut that keeps the fan clutch fastened to the engine, and it can be challenging to remove this nut without the right tools.
A pneumatic fan clutch tool typically has an open-ended wrench on one side and a slot on the other that resembles a hook. To use a fan clutch wrench with an impact hammer, you would first fit the wrench over the large nut. Then, a long metal shaft fitted to the impact hammer is slid into the slot. A short pull on the trigger of the impact hammer is often enough to loosen the nut.
It is important to note that when reassembling the fan drive to the fan hub shaft, you should not use a hammer or any other impact tool to tighten the fan drive, as this may cause thread damage. Instead, you can use the included cap with the impact hammer and strike it with a standard hammer or mallet to tighten the fan drive.
Additionally, always apply force directly and straight to the end of the bar of the impact hammer. Applying force to any other part of the bar may damage non-load-bearing components of the tool.

Fan clutch removal tools
Fan clutches are an essential component of a vehicle's cooling system, engaging when the temperature rises and disengaging once it has cooled down. Removing a fan clutch can be challenging, and often impossible, without the right tools. Various fan clutch removal tools are available, each serving a specific function in the removal process.
Pneumatic Fan Clutch Wrench
A pneumatic fan clutch tool is designed with an open-ended wrench on one side and a slot on the other that resembles a hook. This tool fits over the large nut that keeps the fan clutch fastened to the engine. A long metal shaft attached to an impact hammer is then slotted into the pneumatic fan clutch wrench, and a short pull of the trigger is usually enough to loosen the nut.
Fan Clutch Holding Tool
A fan clutch holding tool is used to hold water pump pulleys in place while the radiator fan is being serviced. This tool is especially useful when physical strength alone is used to loosen the fan clutch nut.
Fan Clutch Spanner Wrench
A fan clutch spanner wrench is designed to hold water pump pulleys in place. It can be used in conjunction with a breaker bar or ratchet to provide the necessary leverage to loosen the fan clutch nut.
Universal Fan Clutch Wrench Set
A universal fan clutch wrench set typically includes a double-ended turning wrench that fits multiple sizes, allowing it to be used on a wide range of vehicles. These wrenches often feature square drive holes that can be used with a hand ratchet or breaker bar to create a handle and apply extra force.
When choosing the right fan clutch removal tool, it is important to consider the specific requirements of your vehicle's cooling system. Fan clutches come in different sizes and designs, so it is crucial to select a tool that is compatible with your vehicle's fan clutch.
